Hi! While testing a stack of burned CD’s with @Waterfuell 's System Disc, I stumbled upon the Sonic Wings Special debug/test menu. (It also erased all my saturn’s internal RAM, ) To access it, simply change “SEGA-TP” to “SEGA-ENT” in the header of the game (I used the Region Patcher v3.0 Gold Edition). I did a google search and found no mention of it, my bad if it is already known. When you boot the game, it will go straight into test mode. Sorry for my bad English.
